NOTE: In Canada when using a factory-built chimney it must be safety listed, Type UL103 HT (2100 o F) CLASS "A" or
conforming to CAN/ULC-S629M, STANDARD FOR 650 o C FACTORY-BUILT CHIMNEYS.
Pro Tips
•
See venting manufacturer's required clearances to combustibles
•
For horizontal installations, the minimum clearance from exterior to termination cap is 6"—you
may want to increase to 18" clearance to minimize soot blow back on home exterior.
Install vent at clearances specified by the manufacturer
WARNING!
Do not terminate venting in any enclosed or semi-enclosed area
such as: a carport, garage, attic, crawl space, under a sun deck
or porch, narrow walkway or closely fenced area, or any location
that can build up a concentration of fumes such as a stairwell,
covered breezeway, etc.

Venting Your Stove
The maximum horizontal venting allowed with no vertical venting
attached is 48 inches including one 90° elbow or two 45° elbows.
Addition of any horizontal venting beyond 48 inches requires a
minimum 60 inches of additional vertical vent. Horizontal sections
of vent pipe should have a 1/4 inch rise per foot. We recommend
using the shortest venting and fewest elbows possible when venting
horizontal.
We recommend the use of 4 inch vent with any installation requiring
more than two 90° elbows, or more than 15 feet of venting.
•
45° elbow is equivalent to 1 foot of straight pipe
•
90° elbow is equivalent to 3 feet of straight pipe

WARNING!
Fire Risk.
•
Only LISTED
venting components
may be used
•
NO OTHER vent components may
be used. Substitute or damaged
vent components may impair safe
operation.
Notice:
These are guidelines for successful
venting of your pellet Stove. The more
vertical rise you can obtain in your sys-
tem, the better it will perform. Horizontal
vent runs can accumulate ash and will
need to be cleaned more often. Try to
keep them as short as possible.
